DUST-SHIELD FOR VEHlCLE-HUBS.

SPECIFIGA TION forming part of Letters Patent N 0. 636,628, datedNovember 7, 1899. Application filed March 30, 1899. Serial No. 711,127-(No model.)

To all whom iv may concern:

Be it known that we, HENRY O. BURCH and JOHN W. WALLING, citizens of theUnited States, residing at Amity, in the county of Yamhill and State ofOregon, have invented certain new and useful Improvements in D ust-Shields; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to dust-shields and the object in View is toprovide an article of the character referred to which is resilient andwhich will accommodate itself readily to a vehicle-hub, yielding to theendwise movement of the hub and at all times fitting snugly and closelyagainst the outer surface of the hub, thereby preventing the admissionof dust, dirt, and other foreign matter to the spindle.

A further object of the invention is to provide a dust-shield of such aconstruction that it will automatically wipe the dust, dirt, and othermatter from the inner end of the hub outward, thereby causing it to fallaway from the hub at a point remote from its inner end.

The detailed objects and advantages of the invention will appear morefully in the course of the subjoined description.

The invention consists in a dust-shield for wheel-hubs embodying certainnovel features and details of construction and arrangement of parts, ashereinafter fully described, illustrated in the drawings, andincorporated in the claims.

In the accompanying drawings, Figure 1 is a perspective View of adust-shield constructed in accordance with the present invention. Fig. 2is a longitudinal section through a hub and spindle, showing theapplication of the improved shield thereto. Fig. 3 is a cross-sectionthrough the axle and dust-shield, showing the clip by means of which theshield is secured upon the axle.

Similar numerals of reference designate corresponding parts in all theviews.

Referring to the drawings, it will be seen that ,the dust-shieldcontemplated in this invention comprises a body portion 1 in the form ofa half-sleeve adapted to fit over the top of an axle and to conform asclosely as possible to the shape of said axle. Extending along the topof said sleeve portion 1 is a metal strap 2, which is secured at itsends to the sleeve 1 and offset at the points 3, so as to leave a space4 between the strap and sleeve, through which the clip (indicated at 5)passes.

The clip 5 is composed of a piece of flat metal provided at one end withan opening 6 for the passage of the other extremity of the clip. Thesaid other extremity (indicated at '7) is substantially round incross-section and is screw-threaded. The body of the clip 5 passesthrough the loop 4, formed by the strap 2, and is thus connected to andkept from being separated from the dust-guard. After the clip 5 ispassed around the axle the threaded extremity thereof is passed throughthe opening in the other extremity and a nut applied to the projectingthreaded end, whereupon by tightening said nut the clip 5 is drawntightly around the axle and caused to bind and clamp the body or sleeve1 fast on the axle.

The particular form of clip hereinabove described enables thedust-shield to be clamped at any desired point on the axle, no matterwhether there are bolts, springs, or other projections present, the clipbeing adapted to embrace any projections of such nature.

At the outer end of the half-sleeve or body 1 is a disk-shaped head 9,which is adapted to abut against the inner end of the hub, (shown at10.) Extending outward and substantially horizontally from said head 9is the shield 11, which is substantially semicylindrical incross-section near its inner end and constructed in laminated form,being composed of two or more thicknesses of spring metal of any desiredgage for imparting to the shield as a whole the necessary resiliency toenable it to conform to the contour of the hub and accommodate itself atall times to the movements and varying positions of the hub. Vhile theinner portion of the shield is semicylindrical, as described, as itapproaches its outer end or extremity it is reduced in width, so as toform a horizontallyprojecting and somewhat obliquely disposed tongue 12.The extreme end of the tongue is of but a single thickness and iscomposed of the inner or under ply or layer of the shield.

The several thicknesses or plies are secured together by suitable rivetsat the proper points.

In view'of the above description it will be seen that the shield proper(indicated at 11 and 12) is composed of plies or thicknesses ofresilient metal, and the flexibility or resiliency of the shieldincreases toward its projecting end or extremity, where the size of thehub also increases. In view of this construction and arrangement it willbe seen that the shield can spring or yield to accommodate itself to theshape of the hub and also to accommodate the hub in its varyingpositions. It will also be noted that the shield on both sides is curvedat the points 13, and the edges of said curved portions are of ogee formand act as deflectors or wipers for wiping the dirt, dust, and otherforeign matter on the outside of the hub toward the outer end of the huband away from the inner end, where the spindle enters. It will be notedthat the innermost layer or thickness reaches farther out on the hubthan the next succeeding thickness, so that the entire edge of the innerthickness, or that which bears directly against the hub, is left to acertain extent unsupported, thereby enabling it to yield readily andconform to the outer contour of the hub.

We do not wish to be restricted to the exact form of dust-shieldhereinabove described, and illustrated in the drawings, but reserve toourselves the right to change, modify, or vary the form and constructionwithin the scope of this invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. A dust-shield for Vehicle-hubs constructed to extend over the innerend of the hub and made in laminated form, the projecting portion of theshield being composed of spring-metal plates of unequal length whichextend one beyond the other over the hub, whereby the resiliency of theshield increases toward its outer projecting end.

2. A dust-shield for vehicle-hubs,constructed to extend over the innerend of a hub and made tapering toward its projecting reduced extremityso as to form inclined or obliquelydisposed edges of ogee form whichserve to wipe the dust and other matter away from the inner end of thehub, substantially as described.

3. A dust-shield for vehicle-hubs, comprising a body portion forembracing an axle, and provided with a loop on its upper side, incombination with a clip consisting of a metal strap passing through saidloop and around the body portion of the shield, one end of said strapbeing provided with an opening and the other end threaded and insertedthrough said opening, where it is provided with a clampingnut.

In testimony whereof we affix our signatures in presence of twowitnesses.
